System design and simulation analysis of RF interference cancellation technology

Based on the co site RF interference between the emission equipment an d the receiving equipment in the C4ISR system, the RF interference cancellation technology is discussed in this paper. Based on the analysis of the theory model , a system design scheme is proposed. The design method of the three main unit, signal adjustment, signal detectivity and sysem control, and the system control arithmet ic are carefully studied. The system model is simulated and the results validate t he system design method which can be used in the further equipment manufacturing.
